Technical Guides
In-depth guides on resin chemistry, process selection, and composite manufacturing best practices.
Post-Cure Cycles for Structural Epoxy Composites: When and Why
A technical guide to when post-cure is required, how it advances Tg and degree of cure, and how to design a safe ramp–dwell–cool cycle.
Gel Time and Pot Life in UPR Systems: What Affects Them
Understand the key factors controlling gel time and pot life in UPR systems — from initiator and accelerator levels to temperature, inhibitors, and fillers.
Gelcoat Application: Avoiding Air Bubbles, Pinholes, and Fish-eyes
Practical controls for gelcoat defects — viscosity, spray technique, mold prep, and contamination — to deliver Class-A composite surfaces.
How to Select Resin Systems for Vacuum Infusion (VARI)
A practical guide to selecting resin systems for vacuum-assisted resin infusion — viscosity, gel time, chemistry, and avoiding common pitfalls.
Fumed Silica as Thixotrope in Epoxy Systems: Dosage and Mixing Guide
Practical guide to selecting hydrophilic vs hydrophobic fumed silica grades, dosage ranges, and mixing protocols for epoxy thixotropy.
Epoxy vs Vinyl Ester Resin for Chemical-Resistant FRP Pipes and Tanks
Epoxy delivers superior solvent and caustic resistance; vinyl ester wins on acid and oxidizer service plus faster cure. Match resin to service chemistry, temperature, and budget.
ATH Filler for Flame-Retardant FRP: Loading Levels and Processing Tips
Practical guide to using ATH (aluminum trihydrate) in unsaturated polyester and epoxy FRP: loading ranges, viscosity control, and processing tips.
Hand Lay-up vs Vacuum Infusion: Process and Chemical Selection Guide
Compare hand lay-up and vacuum infusion processes for composite manufacturing, with resin, curing agent, and additive selection guidance.
Silane Coupling Agents for Fiber Surface Treatment in Composites
How silane coupling agents bond fiber reinforcements to resin matrices, key chemistries, and selection guide for FRP manufacturers.
Cobalt Accelerator Systems for Room-Temperature Cure UPR
Cobalt octoate paired with MEKP enables 20–30 °C cure of UPR. Practical dosing, DMPT booster choice, and failure-mode fixes for composite shops.
